When a TFS changeset has an ampersand (&) character in the comment, the TFS
plugin gets a "Parse Fatal Error" resulting from a SAXParseException. The
result of this is that no changes are shown for the build in the Hudson UI, even
though TFS changesets were found.

Here is an example stacktrace:

SEVERE: Parse Fatal Error at line 6 column 54: The entity name must immediately
follow the '&' in the entity reference.
org.xml.sax.SAXParseException: The entity name must immediately follow the '&'
in the entity reference.
